A method of operating a memory system including a nonvolatile memory, having a meta data region and a user data region, and a memory controller having a meta data manager. The method includes programming data to a memory block of the user data region and, by operation of the meta data manager, generating a meta log based on the programming. The meta log is stored to the memory controller. Upon a power-off operation, selectively storing the meta log to the meta data region of the nonvolatile memory based on status information of the nonvolatile memory.

Method of operating a memory system having a meta data manager

Disclosed is a data managing method of a storage device which includes at least one nonvolatile memory device and a controller controlling the nonvolatile memory device. The data managing method includes receiving an input/output request and generating a section directing logical addresses based on the input/output request. The section is managed using section information, and the section information includes a start logical address corresponding to the input/output request, spatial locality information having the number of the directed logical addresses, and historical request information.

Storage device and data management method thereof

A method of controlling a storage device, the method including calculating, in a controller of the storage device, data throughput of the storage device in a current period, comparing, in the controller, the data throughput to a reference value and adjusting, with the controller, an operation performance of the storage device in a next period based on the comparison and a delay factor of a period prior the current period.

Method for adjusting performance of a storage device and a semiconductor storage device therefor
